Abstract: 985,225. Blanks transferring. ETABLISSEMENTS EHL. LATIC. April 11, 1962 [April 12, 1961], -No. 13971/62. Heading B3B. [Also in DivisionG1] Apparatus for bringing a body A to a pre. determined working position B so that it can be operated on by a cutter 7 or a machine tool comprises irreversible rollers 1 which move the body forward at a fast speed until body A encounters flap G and then at a slower speed. When body A engages the cap 5 of a buffer 3 positioned on an adjustable carriage 2 the cap 5 is depressed. As soon as cap 5 becomes stationary, regardless of the amount it has been depressed hydraulic pressure acts to return it to its original position and the boy A is moved against the action of the rollers 1 to the desired position B.

Title: Sewing machine assembly
IPC: D05B75/04
Filed: 1956-05-07
Abstract: 790,736. Sewing machines SINGER MANUFACTURING CO. May 7,1956 [May 24, 1955], No. 14020/56. Class 112 A sewing machine assembly comprises a machine frame having a bed, machineactuating mechanism carried beneath the bed, a supporting table top formed with an aperture to accommodate the bed, and a drip tray of flexible synthetic plastic material carried by the table top beneath the aperture. Flexible cushioning members are interposed between the bed and the table top. The object of the arrangement is to reduce noise and vibration. A table top 12 is formed with an aperture 11 for receiving the bed 13 of the machine frame. A drip tray 50, fixed within the aperture by means of nails 51, is made from a plastic such as polyethelene or neoprene so as to have a period of natural vibration which is less than audio frequency. The tray is formed with diagonal oil-collecting grooves 58 leading to a sump 59. The looptaker end of the tray is open as at 52, and is formed with a raised lip 60 which may be depressed towards one side or the other to facilitate draining of the tray. An upwardly projecting boss 62 in the drip tray is apertured as at 63 to allow the passage of a presser-lifting connection. The bed may rest upon four rubber blocks disposed at the respective corners of the aperture. As shown, the bed is mounted at the rear on resilient hinge pintles 40 as disclosed in Specification 773,176, and is supported at the front on rubber blocks 30 adapted to be loaded in shear. The blocks are secured in recesses 31 by means of angle brackets 32. In Fig. 4 a metal plate 36, bonded to the inner surface of the block, projects slightly at 37 above a horizontal surface 35 of the block, whereby the bed first makes contact with portion 37, to load the block in shear, before it seats on surface 35. In a modification, Fig. 5, the bed-supporting surface 35 of the block slopes at an angle A of approximately 10 degrees to form an inner edge 38 which first contacts the bed.

Title: Improvements in or relating to electro magnetic relays
IPC: H01H50/20
Filed: 1927-05-26
Abstract: 296,324. Igranic Electric Co., Ltd., and Spaink, J. H. Abbink-. May 26, 1927. Systems for continuous current motors; controllers.-Electromagnetic relays in which the movement t of the armature is retarded by an eddy-current brake have the magnetic circuit of the brake associated with that of the relay in such a manner that increased braking flux is generated by virtueof the approach of the armature to its attracted position. As shown in Fig. 1, the relay has an energizing coil 5 and a rectilinearly movable armature 3a, the movement of the armature driving through suitable gearing an eddy-current disc 6. The magnetic circuits of the relay and of the brake disc ane completed through a common limb 1 which is normally at high flux density so that as the relay air gap x is decreased on the attraction of the armature, the consequent increase in flux causes an increase in the braking flux across the gap y and the increased braking force may thus be made to compensate the increase of attraction of the armature as it approaches its attracted position, the speed of the armature thus remaining practically constant. If, however. an auxiliary coil 7 is placed on the limb 4, in the magnetic circuit of the brake, as shown in Fig. 2, and current in a controlled circuit passes through this coil to assist the braking flux produced by the relay coil, the speed of movement of the armature may be made to vary in accordance with the value of this current If. however, the current in his coil is reversed, provided it does not overcome the magnetising effect of the coil 5 in the magnetic circuit of the eddy-current brake, the effect of the current in the coil 7 may be made to decrease the pull on the armature 3a and at the same time to decrease the braking flux. If the latter effect is made to predominate the armature speed may thereby be increased. Thus the relay may be arranged to control the speed of acceleration of a reversible electric motor at different rates in opposite directions of rotation by arranging the coil 7 in series or shunt with the motor armature.

Tower gas purifiers comprising removable trays stacked one on top of another with the bottom tray supported on a compartment permanently fixed in position with gas inlet and outlet connections have water-seal gas flow control valves within this compartment. In the form shown trays a constitute sections of the tower and incorporate ducts b, d, and lower spaces e for passage of gas to and from the material c. Duct b registers with an aperture 31 in a bottom plate 38, thus communicating with the bottom section 5 into the centre of which is disposed a connection 7 with the crude gas main. An upstanding cylindrical wall 9 from which depends a bell 12 provides a seal for the gas inlet when water is supplied through a pipe 13, the water being drainable through a valved pipe 14. Gas may also be supplied to the section 5 from another purifier through a side inlet 17 which opens into a bell 21 D-shaped in section with a surrounding wall 24 providing a seal supplied with water through a pipe 25. Another seal chamber 33 with a top inlet registering with an aperture 37 in the bottom plate of the lowest tray and thus with duct d provides a closure for. the gas outlet. A water overflow pipe 41 prevents escape of water into the main. When a gas heater is employed the main inlet preferably opens through the bottom plate of the base section adjacent its side wall; a nest of hairpin heater tubes (Fig. 4, not shown) extends horizontally into the upstanding passage surmounted by the seal bell, the heater tubes opening into a shallow chamber divided into an upper and lower header secured over an aperture in the section wall.
